ABSTRACT

The composition of the present invention comprising  Cucurbita moschata, Carthamus tinctorius, Plantago asiatica  and  Lonicera japonica  has a follicle-stimulating hormone reduction action. Based on this action, the composition is usable as a preventive, remedy, health food or functional food for diseases, for example, climacteric disturbance, primary hypogonadism (including ovarian hypofunction and testicular deficiency), Turner&#39;s syndrome, Klinefelter&#39;s syndrome, gonadotropin-producing tumor, testitis, and primary ovarian amenorrhea and/or hormone-producing tumor.

TECHNICAL FIELD

The present invention relates to a follicle-stimulating hormone reduction agent characterized by comprising four kinds of crude drugs, i.e. Cucurbita moschata, Carthamus tinctorius, Plantago asiatica and Lonicera japonica.

BACKGROUND ART

Follicle-stimulating hormone (FSH) is a gonadotropic hormone (GTH) and is involved in the growth of seminiferous tubule and the promotion of semen formation in testis and, in ovary, in the growth and maturation of follicle.

The diseases associated with high amount of FSH in blood included climacteric disturbance (e.g. Hyojunsanfujinkagaku: ISBN: 4260130536, Igakushoin Co., Ltd., Change of Sexual Function and Sexual Organ Form with Aging, p. 23 to 25, 1997). Besides, there are primary hypogonadism, Turner's syndrome, Klinefelter's syndrome, gonadotropin-producing tumor, testitis (e.g. Naikashindangaku: ISBN: 4890132341, Hormone Test, Nishimurashoten, Niigata, p. 843 to 887 1997), primary ovarian amenorrhea, hormone-producing tumor (e.g. Hyojunsanfujinkagaku: ISBN: 4260130536, Igakushoin Co., Ltd., Emmeniopathy B Amenorrhea, p. 34 to 44, 1997), etc.

Description is made on climacteric disturbance which is one of the above diseases.

Climacteric is defined in various ways but it refers to several years before and after menopause. Those diseases which appear in this period, are unbearable physically and mentally and need treatment, are called climacteric disturbance or disorder (e.g. M. Mizuno, Psychosomatic Disorder, Climacteric Disturbance and Health Care of Middle-Aged and Elderly Women, Hyojunsanfujinkagaku: ISBN: 4260130536, Igakushoin Co., Ltd., Tokyo, p. 170 to 175, 1997).

Climacteric disturbance appears in various symptoms and is largely divided into (1) dyshormonism such as metrorrhagia and atrophied vaginitis, (2) vasomotor nerve system disturbance such as burning sensation and palpitation, (3) psychomotor nerve system disturbance such as heaviness of head, headache and dizziness, (4) moetor system disturbance such as stiff shoulder and lumbago, (5) digestive system disturbance such as constipation, inappetence and nausea, (6) urinary system disorder such as thamuria and sense of residual urine, (7) disorder of dermatologic system, internal medicine and urologic system such as perspiration and sense of oral dryness, (8) metabolism disturbance such as emaciation and obesity, (9) perception system such as numbness, and (10) other disturbances (e.g. Hyojunsanfujinkagaku: ISBN: 4260130536, Igakushoin Co., Ltd., Tokyo, 1997). As representative symptoms of the climacteric disturbance, there are known dizziness, indefinite complaint, headache, palpitation, etc. As psychogenic symptoms often seen in the climacteric disturbance, there can be mentioned depression, masked depression, generalized anxiety disorder, panic disorder, somatoform disorder, disorder of estrogen secretion, symptoms of the castrates, etc.

As the therapy for climacteric disturbance, various drug therapies can be mentioned.

Representative of such drug therapies are hormone replacement therapy (HRT), antianxiety drugs and anti-depressants. Meanwhile, there are times that traditional Chinese herbal medicines are used for before-menopause cases wherein menstrual cycle still remains at a certain level, or for postmenopause cases wherein HRT is contraindicated or is not desired. As main Chinese herbal medicines, there can be mentioned Toki-syakuyaku-san, Kami-syoyo-san and Keishi-bukuryo-gan (Current Diagnosis and Treatment, 12th Edition). Tsudo-san which is used only for removal of Oketsu (blood-stasis) in climacteric disturbance, contains a small amount of Carthamus tinctorius but the main component thereof is Japanese angelica root (e.g. T. Tani, Efficacy and Pharmacography of Traditional Chinese medicines, Chapter 17 Crude Drugs for Amelioration of Emmeniopathy, Nanzando Co., Ltd., Tokyo, p. 159 to 168, 1992; S. Koyama, Medical Herbal Extracts of East Asia: A Materia Medica Based on the Classics: ISBN: 4-901767-04-6 C3047, Tsudo-san, Medical Yukon Co., Ltd., Kyoto, p. 453 to 457). It is known that an efficacy for endocrine function is expected by use of Toki-syakuyaku-san (an agent for increasing FSH, LH and progesterone), Keishi-bukuryo-gan (an agent for increasing FSH and LH), Syakuyaku-kanzo-to (an agent for increasing progesterone and testosterone), Unkei-to (an agent for increasing LH-RH and an agent for reduction progeterone), and the like. (e.g. Guideline for Treatment by Traditional Chinese medicines, Obstetric and Gynecological Diseases, Outline of Obstetric and Gynecological Diseases, Midori Shobo Co., Ltd., Tokyo, p. 375 to 426).

Meanwhile, as to Cucurbita moschata, Carthamus tinctorius, Plantago asiatica and Lonicera japonica, respective efficacies are reported as follows. For example, it is disclosed that addition, to a feed, of at least one kind of Cucurbita moschata, Plantago asiatica and Lonicera japonica (particularly, a crude drug comprising these three crude drugs) can prevent, in particular, natural infection of parasites, bacteria and viruses and can achieve higher biophylaxis ability and improved meat and egg qualities. Further, it has been disclosed that a feed comprising four kinds of crude drugs, i.e. Cucurbita moschata, Plantago asiatica, Lonicera japonica and Carthamus tinctorius improves the health conditions, survival rates, quality of egg, and has anti-leucocytozoonosis effect in layers, and anti-New-Castle-disease effect and effects of the decreased numbers of enteric Coccidium and Staphylococcus in the intestine of quails (e.g. U.S. Pat. No. 5,882,672).

A method for producing an interferon inducer from the plants of the genus Cucurbitaceae such as pumpkin has been disclosed (e.g. U.S. Pat. No. 4,421,746). The antiviral activity and anti-tumor activity of interferon inducers extracted from the flowers of Carthamus tinctorius has been disclosed (e.g. U.S. Pat. No. 4,456,597). It has also been disclosed that interferon inducers may be extracted from the flowers of Lonicera japonica, seeds of Plantago asiatica, and the like, and that the extracted interferon inducers are useful for prevention and curative treatments of viral infections in humans and animals (e.g. U.S. Pat. No. 4,469,685). A macrophage activator comprising two crude drugs of Cucurbita moschata and Carthamus tinctorius has also been disclosed (e.g. Japanese Patent Laid-open No. 116498/1999). A neutrophil activator comprising four crude drugs of Cucurbita moschata, Carthamus tinctorius, Plantago asiatica and Lonicera japonica has also been disclosed (e.g. Japanese Patent Laid-open No. 281584/2000).

However, while these documents disclose the interferon inducing effects, macrophage activating effects, neutrophil activating effects, the inhibitory effects of IgE anti-body production, and the like of the crude drugs used as active components in the present invention, none of the references disclose or suggest the effect of reduction FSH level in high FSH concentration in blood.

Clinical Test for Patients with Indefinite Complaint of Postmenopausal Women

An investigation was made on the clinical effect and the action on immune system in cases of indefinite complaint in climacteric. The composition obtained in Reference Example 2 was administered to 32 of the patients exhibiting the indefinite complaint after menopause (with an average age of 53.0±5.1, aged from 48 to 66) for a period of six months in an amount of 6 g on a daily basis. Concentrations of LH and FSH in blood were measured and the symptoms during administration period were examined by Greene's climacteric scale and VAS (visual analog scale).

Incidentally, climacteric scales by Greene, Kupperman, et al. examine the effect on QOL of climacteric disturbance cases and the seriousness of various diseases and evaluate the seriousness. The Greene's climacteric scale was developed in order to examine the symptom of a woman in menopause and is being used clinically in order to examine the reaction directed toward the relaxation of the severity of unpleasant symptom (e.g. Green J G. Constructing a standard climacteric scale. Maturitas. 29, p. 25 to 31, 1998).

Test Results:

Comparison of FSH concentrations in blood before administration and after six month administration indicates that the FSH concentration significantly reduced from 64.05±20.1 mIU/ml before administration to 52.51±18.0 mIU/ml after six month administration(P<0.05). As FSH concentration usually becomes high in climacteric, the reduction of FSH concentration is noteworthy. That is, it is known that the FSH concentration becomes physiologically high level after menopause and this change worsens the symptom of indefinite complaint; therefore, the significant reduce in FSH concentration by administration of the product of the present invention indicates contribution to amelioration of symptoms.

In the evaluation result by Greene's climacteric scale, the (total) score changed from 20.1±9.44 before administration to 12.1±8.46 after six month administration and there was a significant decrease to 60.2% (P=0.0007).

In the evaluation of subjective symptom by VAS, free evaluation of 0 to 100 (0: healthy, 100: maximum pain) was made and recorded by a patient himself or herself before administration and after six month administration, for comparison. The VAS was average 79.2±12.8 before administration and average 32.7±14.1 after six month administration and there was a significant decrease to 41.3% (P=0.0001).

By administering the composition (Reference Example 2) of the present invention for a period of six months, there were significant decrease in climacteric scale and VAS to 60.2% and 41.2%, respectively, relative to the values before administration. That is, the recovering of the scales which is statistically significant decrease (0.07% and 0.01%) indicates obvious relief of patient's QOL.

Thus, it was proven that the composition (Reference Example 3) of the present invention is a FSH reduction agent and it was confirmed that the composition is effective for the treatment of climacteric disturbance or indefinite complaint.

Safety of Health Food to Human

The formulation A of present invention composition:

Components (mixed ratio): Cucurbita moschata (50%), Carthamus tinctorius (20%), Plantago asiatica (15%), and Lonicera japonica (15%)

This formulation A of composition of the present invention was administered to seven male adults twice on a daily basis for a period of two weeks (each does comprised 1.0 g of the crude drug). Blood collection was made before administration and after one and two weeks of administration. Each blood collection was subjected to general clinical tests, i.e. hematology (number of leukocytes, number of erythrocytes, amount of hemoglobin, hematocrit value, MCV, MCH, MCHC, number of blood platelets, and leukocyte fractionation), blood biochemical tests (total protein, albumin, A/G, total bilirubin, MCV, MCH, MCHC, AST, ALT, alkali phosphatase, γ-GTP, total cholesterol, neutral fat, urea nitrogen, uric acid and creatinine), and immunobiochemical tests (nonspecific IgE, nonspecific IgG, and transferrin), as well as to medical examination by. doctor's interview, auscultation and percussion by doctor, and physical tests (body temperature, pulse and blood pressure), whereby the safety of administration of the formulation A of composition of the present invention was investigated. Further, there were measured cell functions [monocyte (macrophage in the blood) phagocytic and neutrophil phagocytic activity, and NK cell activity] and cytokines (IL-2, -4, -6, -8, -10, -12, INF-β and TNF-α), whereby the effectiveness of the present health food was investigated.

The results show that during the two week period of test administration, no adverse effects in clinical test value such as harmful phenomenon considered to have been caused by ingestion of health food, regarding subjective symptoms, objective symptoms or immunobiochemical tests seemed to occur as a result of the administration of the health food of the present invention, thereby confirming the safety of the health food of the present invention. No significant change in cell function and cytokine were observed. It was judged that no measurable could be found in a healthy male at this amount and period of administration.

Example 3

Safety as Health Food

The health food was administered to a healthy male adult for a period of eight years (31 years of age at initiation). For the first two years, the subject was administered a daily average dosage equivalent to 1 g of the powder of the formulation A of composition of the present invention. Thereafter, the subject was administered a health food comprising formulation of composition of the present example at a daily average dosage equivalent to 1 g of the raw powder. The result show that no negative effects to general blood properties or health condition during the period of administration.

INDUSTRIAL APPLICABILITY

The composition of the present invention has an effect for decreasing the amount of follicle-stimulating hormone (FSH) and therefore is useful for the treatment of various diseases associated with high FSH level, such as the followings: climacteric disturbance (e.g. Hyojunsanfujinkagaku: ISBN: 4260130536, Igakushoin Co., Ltd., Change of Sexual Ability and Form of Sexual Organ with Aging, p. 23 to 25, 1997), primary hypogonadism (including ovarian hypofunction and testicular deficiency), Turner's syndrome, Klinefelter's syndrome, gonadotropin-producing tumor, testitis (e.g. Naikashindangaku: ISBN: 4890132341, Hormone Test, Nishimurashoten, Niigata, p. 843 to 887, 1997), and primary ovarian amenorrhea and/or hormone-producing tumor (e.g. Hyojunsanfujinkagaku: ISBN: 4260130536, K.K. Igakushoin, Emmeniopathy B Amenorrhea, p. 34 to 44, 1997).

In addition, the FSH reduction agent of the present invention is useful for the treatment of, in particular, diseases of postmenopausal women said to have a high FSH level, such as climacteric disturbance or indefinite complaint.

Further, the FSH reduction agent of the present invention has improved the subjective symptoms of patients having the above-mentioned diseases and the indefinite complaint diagnosed as such by a doctor. That is, the present FSH reduction agent has improved symptoms of climacteric disturbance or indefinite complaint, i.e. fatiguability, sense of fatigue, apathy, insomnia, nervousness, stiff shoulder, headache, lumbago, and/or malaise, etc.

It is reported that climacteric disturbance reduces the QOL of women significantly and has a great influence on the postmenopausal life of women (e.g. N. Atoyama, Characteristics of Physical Abilities of Climacteric and Elderly Females and Their Disturbances, Nakayamashoten, Tokyo, p. 37 to 76, 2001). It is no exaggeration to say that a key for an postmenopausal women to spend thirty years after menopause in a healthy condition lies in whether or not the women can overcome her climacteric symptom (indefinite complaint) seen in the period (e.g. N. Atoyama, Special Issue: Health Care of Middle-Aged and Elderly Females A. Climacteric Disturbance 15. The Actual State of Outpatients in Climacterium in Our Laboratory, The Gynecology, Treatment, as Outpatients in Climacterium and Postmenopause, Sanfujinkachiryo, Vol. 76, P. 206 to 213, 1998); therefore, the FSH reduction agent of the present invention can be used as an excellent preventive or remedy.
